Abstract

The paper describes the processes associated with sediment deposition in the presence of large blocks of dead or stagnatingice. The study examines a large valley depression in the Grudziądz Basin (lower Vistula Valley) which formed part ofthe area covered by the last glaciation. A detailed description of the glaciolimnic landforms arising in that depositional setting was prepared along with a record of their structural and textural variety and their paleogeographical implicationsare discussed. It is concluded that the whole terrace system of the Grudziądz Basin was mainly formed in the presenceof dead ice.

Keywords: lower Vistula River valley, dead ice landforms, kame terraces, lithofacies analysis, Quaternary, Northern Poland
